' Application filed June 1, 1912. Serial No. 701,043.

To all whom it may concern.-

Be it known that I, EDWIN W. PIERSON, a citizen of the United States, and a resident of Newark, countyof Essex, and State of New Jersey, have invented anew and useful improvement in Typographical Machines, of which the following is a specification.

My. invention has reference to typographical machines, such as line casting machines, wherein a type metal slug or printing bar is cast in a slotted mold against a matrix line presented temporarily at one side thereof and serving to form the type characters on the edge of the slug. In such machines, as represented for instance in U. S. Letters Patent to O. Mergenthaler, No. 436.532, the slug is subsequently delivered from the mold by anejector blade, which advances from the rear and drives the slug out of the mold and into a receiving galleyat the front. In certain types of machine, when at rest and in normal condition, the ejector blade is contained wholly or partly within the mold, as illustrated for example in U. S. Letters Patent to J. R. Rogers, No. 945,609, wherein is also disclosed means which prevent the operation of the parts unless the ejector blade occupies this position. In order to adapt the machine for producing slugs of different lengths, the mold slot is made variable in size, and when the length of the mold slot is changed, the ejector should be adjusted or replaced by another so as to have a width corresponding thereto. To this end, the said Rogers patent illustrates certain manually operable means, whereby the ejector blade may be removed from the mold, and after its change or adjustment may be returned thereto, this return being necessary to permit the regular operation of the parts, as previously indicated. The ordinary commercial linotype machine is equipped with shifting means of this character, and it is necessary therein to restore the ejector blade to normal position by a manual operation.

It is one of the principal objects of my invention to obviate this necessity and to provide means whereby the return is effected automatically. Moreover, the devices are so arranged that they may be conveniently actuated by the operator and without special attention on his part,--the results being that the change or adjustment of the ejector may be more speedily and simply eflected, and that general simplicity and certainty are secured.

. I have illustrated my invention in preferred form and by way of example, and as applied to the specific type of machine already discussed, but obviously many changes and variations may be made therein, and it may be similarly adapted to other forms of typographical casting machines, without departure from its spirit. Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment except in so far as such limitations are specified in the claims.

- The accompanying drawing is a detached perspective view, partly in section, of the mold carrier, ejecting means, etc., with my improved devices embodied therein.

The mold carrier or wheel A is provided with a plurality of slotted molds, such as B and B, and the ejector blade C, which is interchangeable or adjustable to different sizes of mold slot, is actuated by the reciprocating slide D, all in the usual manner. The slide D is connected by the link E to the operating lever F, which is moved by the customary actuating devices comprising the cam F Rigidly connected to the lever F is an arm F which in turn is connected to the slidable rod G extending forwardly to the front of the machine. As illustrated in the drawing, the ejector blade C is normally contained within the mold B the latter being shown with its cap removed. In the event of a change of mold, it becomes necessary also to alter the dimensions of the blade C, and to effect this, the rod G is manually moved to the rear to withdraw the blade from the mold. After the change or adjustment of the blade, the rod G is moved in the opposite direction to return the blade within the mold, and thus to leave the mechanism in condition to operate.

All of the parts and operations so far described are or may be similar to those empreferably: employ the treadle H, which is located in convenient position to be actuated by the foot of the operator, thus leaving his hands free, and-further obviating the necessity for his leaning over to operate the rod G. The treadle H- is pivoted at H to. the

frame of the machine, and is provided with a notched arm L adapted to engage the piece or block K on the rod G, in such manner that the actuation of the treadle first causes the engagement of the parts L and K, and then moves the-rod rearwardly to withdraw the ejector blade from the mold. The treadle is returned to its normal position. after its actuation and subsequent release, by the spring H which also acts to disengage the notched arm L from the piece or block K. The return movement of the ejector C is eflected, through the connections described, by the action of a spring J upon the collar J fast on the rod G. In order to permit the manual actuation of the rod G in the ordinary manner, if desired, and to prevent the. pressure of the spring J from being constantly imparted to the connected parts, I provide a temporary abutment therefor, which allows the spring to be placedunder tension only at the time when the treadle is actuated, this occurring when the parts are at rest and when it is desired to change or alter the adjustment of the ejector blade. These means comprise a lever M pivoted at M to the machine frame, one end of which lever is arranged in proximity to theend of the spring J, and the other end of which carries a pivoted latch O. The latch O is formed at oneend with a notch 0 and at the other end is provided with a spring 0 which tends to move the latch in such manner as to bring the notch 0 into temporary engagement with some movable part of the machine, such for instance as the arm R, this upward movement of the latch 0 being normally resisted by the contact with the arm R of the portion 0 of the latch lying beyond the notch. The treadle H is pivotally connected to one end of a link N, the other endof which link is connected by a pin-and-slot N to the lever M. v v

The operation of the parts is asfollows: When the treadle H is actuated, it is moved about its pivot H against the force of the spring H, the. first effect of such movement being to bring the notched arm L into engagement with the piece or block K on the rod G. Simultaneously therewith, the link N is moved longitudinally to bring it into operative relation to the lever 151, the pinand-slot N permitting a certain amount of .lost motion. The further actuation of the treadle, due,to the engagements described, results in the longitudinal movement of the rod G and the pivotal movement of the lever iaaeaas has also effected the compression of the spring J between the collar J and the end of the lever M, which was simultaneousl moved in the opposite direction by the lin N. The treadle H is then held by the foot of the operator, while the ejector blade is being changed or adjusted, after which it is released, and the compressed spring J then acts to restore the rod G, and, through the described connections, the ejector to its normal position within the mold B The return of the latch O and the lever M to normal position, and the consequent release of the spring J from operative contact with the end of the lever M, are permitted by the subsequent upward .movement of the arm R, which is mounted upon the shaft P carrying the line delivery lever Q. The selection of the arm R to engage with the notch O is simply a matter of convenience, and in order to utilize some periodically operated part of the machine to engage with and disengage from the latch 0, there being otherwise no particular connection between the line delivery devices and the ejector adjusting means.

As previously stated, I have shown my invention in preferred form and by way of example, but obviously many modifications and alterations therein will suggest themselves to those skilled in the art and still be comprised within its scope.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by'Letters Patent of the United States. is as follows:

1. In a typographical casting machine, the combination of a power-actuated ejecting device, means operable at will for moving the said device from its normal position of rest, and automatic means for returning it to such position, the said means being arranged so as .to be inactive during the power-actuated movements of the ejecting device.

2. In a typographical casting machine, the combination of a power-actuated ejecting device, means operable at will for moving said device from its normal position of rest, and a spring for returning it to such position, the said spring being arranged so as to be inactive during the power actuated movements of the ejecting device.

3. In a typographical machine comprising casting mechanism, the combination of an e ecting device, means operable at will for moving said device from its normal poanaaaee sition, and means for automatically returning it, the said returning means adapted to be rendered active by the operation of the first mentioned means.
